Sanna batter
Sannan (singular) · Sanna batter is a fermented rice-and-coconut batter of Goan and Mangalorean origin, traditionally leavened with coconut toddy or, in modern practice, dry yeast. It is the foundational preparation used to steam soft, pillowy savory cakes (singular sannan; plural sanna) that accompany curries and festive meats.
The formula
parboiled rice : urad dal ≈ 4:1 (Hindu style); rice : grated coconut ≈ 3:2 (yeast style); toddy/yeast ~1 tbsp per 2 cups batter
Two principal formulas exist: a Hindu-style batter that incorporates urad dal as in idli, and a Catholic-style batter relying on toddy or yeast for leavening with grated coconut or coconut milk for body.
Identity
- Fermented, not chemically leavened — uses toddy or yeast as living culture
- Contains coconut (fresh grated or coconut milk), distinguishing it from idli
- Steamed, never pan-fried or baked
- Pillowy, soft, whiter and lighter in crumb than standard idli
- Mildly sweet background from added sugar
- Religious-community marker: Catholic homes traditionally used toddy; Hindu homes used urad-dal fermentation
Ingredients
| Base | Parboiled rice (ukda tandul) or idli rice or Goa red rice | Soaked 4–6 hours; Goa red rice gives distinctive red streaks and earthy flavor; parboiled/idli rice is the standard substitute. |
| Base | Urad dal (split, husked) | Used in the Hindu-variant sanna to provide fermentation lift and aeration; omitted in Catholic-style toddy/yeast versions. |
| Enrichment | Grated fresh coconut or coconut milk | Defines sanna and separates it from idli; lends richness, moisture, and subtle sweetness. |
| Leavening | Coconut toddy (fermented palm sap) OR dry active yeast | Toddy is the traditional Catholic-community leaven; modern kitchens substitute 1–1.5 tsp dry yeast activated in lukewarm water with sugar. |
| Sweetener | Sugar | Feeds the yeast and yields the signature mildly sweet flavor; about 2 tbsp per 3 cups rice. |
| Seasoning | Salt | Added after fermentation; balances sweetness and enhances flavor. |
| Liquid | Water (lukewarm for yeast activation; cold for grinding) | Quantity adjusted to reach a thick, pourable, idli-batter consistency. |
Method
- 1Soak parboiled rice (and urad dal if using) in plenty of water for 4–6 hours.Hydration softens the grains for a smooth grind and preps starches for fermentation.
- 2Drain and grind the rice with grated coconut (and soaked urad dal) using minimal water to a thick, smooth, fluffy batter.Coconut must be emulsified into the batter to deliver sanna's signature richness; aeration during grinding helps the final lift.
- 3Activate yeast in 2 tbsp lukewarm water with 1 tsp sugar until frothy (skip if using toddy).Proves yeast viability and jump-starts fermentation.
- 4Stir yeast slurry or ~2 tbsp toddy plus remaining sugar into the batter; cover and ferment 6–8 hours (overnight) in a warm place.Live culture produces CO₂ that leavens the batter and develops the mildly tangy, sweet aroma.
- 5After fermentation, fold in salt gently without deflating the batter.Salt regulates yeast activity; deflating after salting preserves trapped gas for a pillowy crumb.
- 6Pour batter into greased idli molds or ramekins and steam 10–15 minutes until a toothpick emerges clean.Steam sets the structure gently so the cakes stay soft and springy.
Techniques that matter
Soaking and wet-grinding
Produces a smooth batter with intact starch granules that trap fermentation gas evenly.
Overnight ambient fermentation
Develops the characteristic mild tang, complex aroma, and airy crumb central to authentic sanna.
Gentle folding after salting
Preserves CO₂ pockets so the steamed cakes rise pillowy-soft rather than dense.
Steaming in small individual molds
Cylindrical ramekins or idli plates give sanna their signature muffin/cake shape and even cooking.
Variations & derivatives
Catholic-style toddy sannaGoa and Mangalorean Catholic homes
Uses rice + grated coconut + coconut toddy for leavening; no urad dal; traditionally served at feast-day tables.
Hindu-style urad-dal sannaGoan/Mangalorean Hindu homes
Rice + urad dal (~4:1) + coconut; fermented via dal enzymes, mirroring idli technique but enriched with coconut.
Yeast-leavened modern sannaUrban kitchens across India and diaspora
Dry yeast replaces toddy for a reliable, neutral-tasting leaven; recipe popularized by Shireen of Ruchik Randhap and others.
Coconut-milk sannaCoastal Karnataka / Mangalore
Swaps grated coconut for coconut milk for a finer, whiter crumb.

Substitutions
- Goa red rice → Parboiled (idli) rice — Most accessible substitute; loses the red streaks and slightly earthy flavor.
- Coconut toddy → Dry active yeast — Standard modern swap; use ~1 tsp yeast per 2 cups batter, activated with sugar.
- Grated fresh coconut → Coconut milk — Yields a finer, whiter crumb; reduces texture contrast from coconut shreds.
- Fresh grated coconut → Desiccated coconut (rehydrated) — Workable but less aromatic than fresh.
- Urad dal (in Hindu variant) → Additional yeast or toddy — Removes idli-like structure; result is softer but less traditional.changes result
Troubleshooting
Dense, flat sanna with no rise
Yeast was dead, batter was over-mixed after salting, or fermentation was too short/cold. → Proof yeast in warm water with sugar first; ferment in a warm spot 6–8 h; fold salt in gently at the end.
Sour or alcoholic off-flavor
Over-fermentation, especially with toddy or in very warm climates. → Reduce fermentation time to 5–6 h, or refrigerate batter as soon as it doubles; steam immediately after the final mix.
Sticky or gummy center
Batter was too thick, or steaming time was insufficient. → Thin batter with a little water to thick-pourable consistency; steam a full 12–15 min and test with a toothpick.
Cracked or coarse surface
Batter was too dry during grinding, or idli molds were under-greased. → Use minimal water during grinding to keep batter loose; grease molds generously with oil.
